'ATTACHABLE VALVE.

.Appiication filed June 15, 922. serial No. 568,524.

To all whom it ma canc @m Be it known that 1, WILLIAM R. CLARK, a citizen of the United States, residing at San Diego, in the county of San Diego and State 1 of California, have invented a new and useful Attachable Valve, of which the following is a specification.

This invention relates to devices for closing in a sanitary manner any cans after once being opened, but the contents of which are not always used at one time, such as cans containing condensed milk, or any other similarly preserved liquids; and to devices for avoiding evaporation of liquids.

One of the objects of this inventionfis to provide a device by which a can may be opened, and, after opening, may be kept closed in a sanitary manner.

' Another object is to provide a device by which the liquids may be poured from the can. v

' Another object is to provide a device which will automatically keep the can closed when no liquid is poured out.

Another object is to provide a device which will automatically close an opened can again after being applied to the can.

Another object is' to provide convenient handling means on the device.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which 3 Fig. 1 is a top plan view of an ordinary can containing condensed milk, having the bar member of the device applied in proper position.

Fig. 2 is a longitudinal midsectional view of the assembled device in the simplest form.

Fig. 3 is a detail fragmentary longitudinal midsectional view of a valve in a slightly modified form. V p f d Fig. 4 is a detailfront' elevation of the controlling valve of the spout end of the device.

Fig. 5 is a detail fragmentary side elevation of a handle with operating connection for controlling the discharging valve.

Fig. 6 is a section on line 6-6 of Fig. 5.

Canned goods are used very much in a household, but it is not always possible, nor desirable, nor practicable to use the whole contents of a can or to empty a can fully on opening the can.

Especially milk cans, holding condensed milk, are very commonly used for several days after being opened. It is with" such cans and any other liquid containing cans from which th contents are used upfrom day to day, and the contents of which should 'be preserved-in good ondi-tion,that a, device as disclosed hereby is of great use and advantage. v

The circle 7 in Fig. 1 designates the centour in top plan view of'a can. The bar member 8 is placed on top of the camhaving a hook-like termination 9 on one end, to engage over the side of the can, and having a threaded termination at the other end 10, for adjustably receiving another engaging member. In Fig. 2, the second engaging member 11 is illustrated in proper engaging position. Both engaging members 9-and 11 are provided with a tapping member 12. The tappingm'ember is of pointed designto easily puncture'or pierce the material of a can, and is preferably hollowed orbored out, as indicated at 13, having communicating perforations 1 1, so that a communication may be establi'shed with the inside of a can through the tapping member. The communicating perforation can be in the pointed end of the tapping member, but, this would, of course, require more effort in piercing a can.

The engaging end 9 isprovided with communicating conduits 15 and 16, controlled by the check valve 17 The check valve 17 is illustrated in its normal closing position, which position it maintains and takes whenever the can to which the device is applied isfplaced in the normal up and down position. When the can is tilted for the purpose of discharging liquids from the other engaging member, the check valve is liable to "move and normally moves to theflposition indicated in dotted lines at 18 so that free communication is established fro'ni the'outside, through conduits 16 and 15, I and through the tapping member 12, with the inside of the can. Air may pass into the can in this manner, in order to facilitate the discharging of the liquids in the can.

The other engaging member 11 is slidably mounted on the pin or screw end 10 of the bar member 8. It is also provided with a conduit, indicated at 19, in communication with the hollowed out tapping member 12. A manually operated valve 20 is provided for controlling the communication through the conduit 19. The valve 20 is pivotally supported at 21, and terminates in a thumb- ,wing-nut 24: is then tightened, to force the pointed tapping members 12 through the sides of the can, until the engaging members tightly engage overthe can. The can with the device is then ready for use. Tilting the can towards the side with the slidable engaging member, the valve 20 is opened by a touch on the end 22, allowing the fluid in the can to pass out and discharge through the perforated tapping member and through the conduit 19, while air is allowed to "enter the can through the conduits 16 and in connection with the tapping member in the engaging member 9, as described above.

' On placing the can back to standing and storing or resting position, the check valve 17 closes automatically, and the valve 20 is'closed by releasing the end 22. Though the can is now pierced and opened, no air can enter the can as long as in such resting position.

Having referred to milk cans in particular, it will easily be understood that this device can be used in connection with many other fluid or liquid containing receptacles, whether the contents are to be protected and maintained in their original well preserved state, or that the contents are to be protected against evaporating, as with hydrocarbons.

In Fig. 8, a slightly modified form of valve for discharging liquids from a receptacle is illustrated, to be used in place of the manually operated valve. This slightly modified form operates on a similar principle as the valve in the engaging end 9 of the bar member 8, the only difference being. that this valve opens to allow a discharging from the container instead of allowing air to pass into the container. The valve member normally rests in the position in which it is illustrated, thereby shutting ofi communication through the conduits 26 and 27 and through the tapping member 12.,, while it may move to the posi tion indicated in dotted lines at 28, to free such communication.

The slightly modified form of handling means, illustrated in Figs. 5 and 6, serves to tacilitatea proper handling of the device in connection with smooth cans. The handle member 29 is disposed to come on the side of a can in a similar manner as the handle of a drinking cup, the head member 30 of the push bar 31 is then in aposition to be easily reached by the thumb'of the hand that is being used, and, a pushing of the bar 31, tending to tilt the end 22 of the valve 20 in a similar manner as described above. The end 32 merely slides over the end 22 of the valve 20. The end or portion 33 is slidably mounted on the bar 8.

Having thus describedmy invention, I claim:

1. In a device of the class described, a bar to be placed on the top "of a liquidholding container having a hook-like end to reach over one side and terminating at its other end in a threaded portion to extend over the opposite side of the container, a valve controlled hollow piercing member in the hook-like end of the bar, and another valve-controlled hollow piercing member adjustably mounted on the threaded end of the bar.

2. In a device of the class described, a bar having a hook-like termination in form of a valve-controlled hollow piercing member at one end to reach over one side of a can and having-a threaded termination on the opposite end to extend over the opposite side of the can, a second valve-controlled hollow piercing member adjustably mounted on the threaded end of the bar, anda nut member on the end of the bar for adjust-' ing the second-named members in relation to the first piercing member for firmly engaging the bar to the can.

In testimony that I claim the foregoing as my invention I have signed my namein the presence of two subscribing witnesses.
